Serbia spends approximately $1.6 billion on defence — around 2.2% of GDP — pursuing a unique multi-vector procurement strategy that combines Western, Russian, and Chinese weapons within a single force. Non-aligned militarily, Serbia has signed a landmark deal for 12 Rafale F4 fighters while retaining Chinese FK-3 air defence and Russian Pantsir-S1 systems, reflecting its position between NATO, China, and Russia as the Kosovo dispute remains unresolved.
Serbia's defence budget has expanded rapidly since 2021, driven by government rhetoric about regional instability and the Kosovo standoff. The official 2025 defence appropriation is approximately 220 billion RSD (~$2B), with supplementary procurement funded through government bonds and Chinese concessional credit. The Rafale F4 deal, signed in November 2023 for 12 jets at an estimated €3 billion, will dominate procurement budgets through 2030 with deliveries from 2028. Serbia targets NATO's 2% GDP benchmark despite not being a NATO member — partly to signal Western alignment while maintaining Russian and Chinese ties. Ammunition export revenues from Krušik and Yugoimport partially offset import costs.
The Serbian Armed Forces (Vojska Srbije) field approximately 28,150 active personnel across the Army, Air Force and Air Defence, and River Flotilla. The Army is organized around three brigades (1st Guards, 4th, and 53rd) with Soviet/ex-Yugoslav armour including T-72 tanks and BVP M-80 IFVs. The Air Force operates MiG-29M fighters alongside the new Dassault Rafale F4 aircraft expected from 2028. Air defence integrates Chinese FK-3 (HQ-22) long-range systems, Russian Pantsir-S1 SHORAD, and legacy Neva/Buk systems — a politically complex mix that creates NATO interoperability challenges. The Danube River Flotilla maintains riverine patrol capability.
Serbia maintains a significant legacy defence industry rooted in the former Yugoslav military-industrial complex. Yugoimport-SDPR acts as state arms trader and developer; Krušik (Valjevo) produces artillery ammunition sold to Ukraine via third countries; Zastava Arms manufactures small arms for domestic and export markets. Serbia became a significant ammunition supplier during the Ukraine war — indirectly, through re-export via third-party brokers — generating revenue that has funded modernization. The domestic industry cannot produce aircraft, advanced air defence, or precision-guided munitions, making Serbia import-dependent for major platforms. A €150M domestic armoured vehicle modernization programme (Lazar 3 APC) is ongoing.
Serbia's principal security flashpoint is Kosovo, whose 2008 independence Serbia does not recognise. Tensions escalated sharply in September-October 2023 when Serbian security forces massed near the Kosovo border following a militant incursion in Banjska that killed a Kosovo Police officer; NATO's KFOR reinforced its presence. Serbia and Kosovo signed an EU-mediated implementation annex to the Ohrid Agreement in March 2023 but neither has fully complied. Serbia formally maintains military neutrality — it does not seek NATO membership — while cooperating with Russia on traditional ties and with China on infrastructure and arms. Conscription was abolished in 2011 but a reserve mobilization system remains.
Serbia signed the €3 billion Rafale F4 contract with France in November 2023 — the first Western fast jet purchase in Serbia's history, with 12 aircraft for delivery from 2028. Chinese FK-3 air defence systems became operational in 2023-24, drawing NATO concern. KFOR reinforcements following the Banjska incident (September 2023) briefly raised regional tensions to a post-war high. In 2024-25 Serbia conducted joint exercises with both Russian forces (cancelled after EU pressure) and with US forces under the Platinum Wolf series. President Vučić sought to balance EU accession rhetoric with continued arms diversification through 2025.
Serbia spent approximately $1.6 billion on defence in 2025 (around 2.2% of GDP) per SIPRI estimates. Spending has grown rapidly since 2021, with the €3 billion Rafale F4 purchase dominating the procurement pipeline through 2030.
The Rafale F4 purchase signals a Western pivot in procurement and strengthens Serbia's case for eventual EU integration, while providing a generational upgrade from aging MiG-29s. Serbia retains Russian and Chinese systems simultaneously — a deliberate multi-alignment strategy.
Kosovo remains Serbia's principal security flashpoint. The Banjska incident of September 2023 triggered the largest NATO KFOR reinforcement since the 2000s. Serbia does not recognise Kosovo's independence and maintains forces capable of rapid border deployment, though direct military action would risk NATO intervention.
Yes. Yugoimport-SDPR and Krušik export artillery ammunition, small arms, and military vehicles. Serbia became a notable indirect supplier of ammunition to Ukraine via third-country re-exports during the Ukraine war, generating foreign exchange that funded domestic procurement.
